Chemoselective oxidative synthesis of N-(2-aminophenyl)imines from 2-amino-N-benzylanilines was accomplished through combined use of O2(air) and copper salt. This transformation was performed at room temperature, and the mild oxidation was efficient and chemoselective without using nitroxyl radicals and ligands.

A highly efficient synthesis for possessing 7-membered rings with two heteroatoms is described, using efficient microwave-assisted one-pot method to synthesize (substituted) dibenzo[b,f][1,4]thiazepines [1] and dibenzo[b,f][1,4]oxazepines [2] in high yields (up to 99%) by cyclocondensations of o-aminothiophenol or o-aminophenol with o-halobenzaldehydes, o-fluoroacetophenone, and o-fluorobenzophenone. In the absence of base, o-aminothiophenol reacted with o-halobenzaldehydes to afford benzothiazoles.
